The actuator consists of a power-driven shaft 18 rotatively. mounted inthe machine frame and extending transversely thereof near the forwardends ot the levers 8, and having at one end outside of the frame 16 adrive wheel or pulley 19, connected in any suitable .manner to a sourceof power, in the present instance indicated as a belt 20 pass ing'around said pulley l) and connected to a` motor (not shown). Secured atintervals along; said shaft. itl is a series of disks or wheels 20through which passes a rod 21 to from trips to engage the latches l0 andpull them downward and thereby operate the tyi'ie-bar operating leversThe operation is sul'istantially as follows; Assuming the parts to be inthe positions indicated in Fig. 1, the actuator continuously rotates inthe direction of `the arrow. Upon one ot' the finger keys 12 of theselective mechanism being struck, the same as in the operationofthekey-board of the usual typewriting` machine, the stem 18 engageswith a lip 22 on the connector or latch 10 and swings the latch on itspivot 23, so that the hook portion 11 projects into the path of the trip2l (Fig. 2). Thetrip vas it rotates engages the latch and exerts adownward pull. upon vthe lever El, throwing` the type-bar up against theplaten. The actuatorl pulls the latch down until au inclined portion 2ston said latch engages with a universal let-off 2:3, in the torni of arod eX- tending transversely ot' and adjustably seicured in slots 25 inthe machine trame 16. The parts are now in the positions illustrated infull lines -in Fig. 3. As soon as the trip is disengaged :trom the latch10 said latch is moved out ot the path of the .'actuator by a spring 26and returned to the normal position (F l) and held by said spring' 26 inidle position against the stop bar 2'? to prevent repeated f-mgagementol' the trip with the latch and the consequent repeated operation et thety1fe-baiz lo prevent repeated engagement of the latch by the trip,should the finger of the operator be accidentally orvunconsciously leftupon the key l2 att-cr it has been de'- provide the latch twith a pin28. to cooperate with a stationary by-pass pin or Ward 29 about whichthe p'in 28 moves in an irregular orbit. The try-pass pins 29, on'e ofwhich is provided t'or each latch,

may be supported on the machine frame in any convenient manner, as forexample, by 'being' secured to arms or standards 1G rising :from thehase ot the machine frame. Should the operato1"s linger remain on the 6Gdepressed key, as already stated, after the coupler or latch has beentripped, the latch is snapped outl of the path of the revolving'actuator or driver by the sprina 2G, and into engagement with the stopbar 27. Thc

lever S and latch 10 move upward until the latch strikes the key stem 13(Fig. 4), the pin 28 being brought by this movement to a position behindthe by-pass pin 2f).4 The latch 10 is held in this position, while thekey 'l2 remains depressed, being prevented from 'farther upward movementby the stem 13, and from for Yard movement about its pivot by the pin29.

lt will lle obvious that when the latch is tripped by the actuator aquick stroke may be imparted to the type-bar 1, the connection ot theactuator with the latch being maintainerfl until the type has reached ornearly reached the platen and a consequent powerful type impression madeagainst the platen. lVhile this powerful blow ofthe ty] 1, against theplaten is essential in some instances, as in doing manifold work anumber o'j carbon shoe 1s in addition to the usual sheets being in themachine, it would be a disadvantage when only a. single sheet is to bewritten upon. To orercmnc this disadvantage I provide means for varyingror regulating the degree ot the type blow the actuator is rotating athigh or low against the platen irrespective of whether speed. This isaccomplished by the adjust?. i

ment of the universal leta'vliY 25. lly adjustingsaid let-oil to theright, it will be obvious that when the inclined portion 24C of thelatch engages therewith and gis thrown out of engagement with the trip21, a down- \'ard pull of considerable extent will have been imparted tothe type-bar operating lever S and a conselpientheavy blow of the typeagainst the platen. However, should the letolt be adjusted to the leftthe latch 1() will he thrown out of engagement with the trip after onlya slight downwardl pull is exerted upon thelever 8 and ay consequentlight blow ot the type againstrthe platen.

Variations may bc resorted to within the scope ol the invention, andportions of the improvements may be used without others.

l'laving` thus described my invention, I claim:

l. ln a typewriting machine, the combination with a power drivenactuator,'o a series of type-bar levers; latches pivoted to said leversand having hook portions; a fixed stop with which said latches normallyengage; depressible linger keys having stems mounted 'for verticalmovement and adapted to engage withthe latches when depressed to throwthe hook portions of the latches into the path o'l the actuator to beengaged thereby to operate the tif'pe-bars; a universal letoli'whichsaid latches engage lo throw them out of eiifrag'cmcnt with theactuator; pins carried by saidv latches; lixed by-|mss pins about whichsaid' latch pins move through their normal orbit of movement; andsprings to return the latches to normal position against the fixed stopout of the path of the actuator..
